PARIS, April 22 (Xinhua) -- Heavy load launcher Ariane 5 lifted off two communication satellites, Yahsat Y1A and Intelsat New Dawn, at around 6:37 p.m. local time (2137 GMT) on Friday from Europe's Spaceport in French Guiana.Yahsat Y1A is the first United Arab Emirates satellite launched by Arianespace. It is built by Astrium and Thales Alenia Space and will be positioned at 52.5 degrees East. With a design life of 15 years, it will be operated by the Al Yah Satellite Communications Company, a telecommunications company indirectly controlled by the Abu Dhabi Government.Weighing around 5,935 kilograms at lift-off, Yahsat Y1A was expected to be separated first around 27 minutes after the launcher started the flight.The second passenger Intelsat New Dawn was built by Orbital Sciences Corporation and weighs about 3,000 kilograms. Also with a designed life span of 15 years, it is planned to be positioned at 32.8 degrees East.Via the second mission of Ariane 5 in 2011, Yahsat Y1A will provide customized relay services for the government and commercial sectors in the Middle East, Africa, Europe and Southwest Asia, while Intelsat New Dawn will work as a part of the global Intelsat fleet, offering service for Africa.This launch, the 201st of an Ariane family vehicle since 1979, brought to 22 the number of Intelsat satellites serving Africa, according to the launching company.Originally scheduled for liftoff on March 30, this dual-payload mission was delayed following an interruption of the final countdown when an incorrect displacement of one of the engine's actuators was detected, Arianespace said in a statement. The launching center planned to have six liftoffs of Ariane 5 through this year.

LOS ANGELES, April 6 (Xinhua) -- Freeze-dried strawberries may play a role in the prevention of esophageal cancer, a new study suggests."Strawberries may be an alternative or work together with other chemopreventive drugs for the prevention of esophageal cancer," said lead researcher Tong Chen, M.D., Ph.D., assistant professor, division of medical oncology, department of internal medicine at the Ohio State University.Study findings were presented at the ongoing 102nd annual meeting of the American Association for Cancer Research (AACR) in Orlando, Florida, according to the American Association for the Advancement of Science (AAAS) on Wednesday."We concluded from this study that six months of eating strawberries is safe and easy to consume. In addition, our preliminary data suggests that strawberries can decrease histological grade of precancerous lesions and reduce cancer- related molecular events," said Chen, who is also a member of the Molecular Carcinogenesis and Chemoprevention Program in the Ohio State University Comprehensive Cancer Center.The study involved a group of participants who consumed 60 grams of freeze-dried strawberries daily for six months and completed a dietary diary chronicling their strawberry consumption.The researchers obtained biopsy specimens before and after strawberry consumption. The results showed that 29 out of 36 participants experienced a decrease in histological grade of the precancerous lesions during the study.Using freeze-dried strawberries was important because by removing the water from the berries, they concentrated the preventive substances by nearly 10-fold, Chen said.Esophageal cancer is the third most common gastrointestinal cancer and the sixth most frequent cause of cancer death in the world, she noted.Chen and her team are studying esophageal squamous cell carcinoma (SCC) which makes up 95 percent of cases of esophageal cancer worldwide. China, where this study took place, has the highest incidence of esophageal SCC, according to the AAAS.In a previous study, Chen and colleagues found that freeze- dried strawberries significantly inhibited tumor development in the esophagus of rats. Based on these results, they embarked on a Phase Ib trial that included participants with esophageal precancerous lesions who were at high risk for esophageal cancer."Our study is important because it shows that strawberries may slow the progression of precancerous lesion in the esophagus," Chen said.But she said they need to test this in randomized placebo- controlled trials in the future.

BEIJING, Feb. 12 (Xinhua) -- The Chinese government has reiterated a strict ban on hepatitis B tests during pre-employment physical examinations as many companies reportedly violated rules to require hepatitis B tests for job applicants.In a statement released Saturday, the Ministry of Health said that no health institutions are allowed to provide hepatitis B checks as part of pre-employment physical tests regardless of whether the examinees provide consent or not.On Feb. 10, 2010, the Ministry of Health, the Ministry of Education and the Ministry of Human Resources and Social Security jointly issued a circular demanding the cancellation of the hepatitis B tests during the health checks for school enrollment and employment nationwide.However, according to a survey released this week, which was conducted by the non-profit Beijing Yirenping Center, some 61.1 percent of the 180 state-run companies surveyed included hepatitis B checks in their pre-employment physical examinations.More surprisingly, 63 companies said that they would never consider hepatitis B carriers for a job or were reluctant to hire such people.Yu Fangqiang, the principal of the Yirenping Center, said that such violations mainly resulted from light punishment for violations and some health institutions' desire for profits.According to the survey, employers would only be fined between thousands to tens of thousands of yuan if they lose their lawsuits for bias against hepatitis B carriers.Meanwhile, a worker will spend a lot of time, energy and money to file a lawsuit and collect evidence in order to win.Liu Xiaonan, an associate professor with the China University of Political Science and Law, called on the government to hammer out a particular law and set up a special committee to investigate discrimination cases in order to ensure the rights of workers.In the statement released Saturday, the health ministry also ordered a careful investigation of all cases of hepatitis B discrimination, and promised that violators would be exposed and punished in accordance with laws and regulations.Medical tests show that hepatitis B virus can only be transmitted from mother to child during childbirth or by contact with the blood or other body fluids of an infected person.

BEIJING, Jan. 23 (Xinhua) -- Chinese President Hu Jintao's state visit to the United States, during which he reached important consensus with U.S. President Barack Obama on building a cooperative China-U.S. partnership based on mutual respect and mutual benefit, has been closely followed by world media.The visit has drawn "unprecedented" world attention, said Gu Xuewu, director of the Center for Global Studies at the University of Bonn.NEW CHAPTER IN DEVELOPMENT OF CHINA-U.S. TIESCommenting on Hu's visit, which occurred at the beginning of the second decade of the 21st century, Professor Severino Cabral, director of Brazil's China and Asia-Pacific Research Institute, said the visit opened a new epoch for China-U.S. relations.The resumption of dialogue between the world's two major economies, which itself is a significant event, would exert great influence on the new world agenda, and hopefully help eliminate the residual cold war mentality and take bilateral relations to a new era, he said.Chen Kang, professor at Lee Kuan Yew School of Public Policy at the National University of Singapore, said that the joint statement issued by the two sides during Hu's stay -- built upon bilateral efforts to establish a cooperative partnership based on mutual respect and mutual benefit -- is a clear reflection of the two countries' resolution and pragmatic attitude in jointly meeting global challenges.China Press USA, a New York-based Chinese language newspaper, said in an editorial that the two countries' commitment to building an all-round and mutually beneficial, win-win economic partnership, as put in their joint statement, is the greatest achievement that comes out of the meeting between the leaders of the two countries in the economic sphere.Nouvelles D'Europe, a major Chinese language newspaper in France, said in an editorial that Hu's visit yielded fruitful results which are indispensable to world peace and development.In their joint statement, the two countries for the first time defined that China-U.S. partnership is based on mutual respect and mutual benefit. Stable China-U.S. relations contribute to world stability, and a win-win scenario between China and the United States is conducive to a scenario of multi-party-win in a multipolar world, it said.International Daily News, an Indonesian newspaper, said that Hu's visit achieved a historic breakthrough. Their joint statement signaled a new chapter in their "cooperative partnership based on mutual respect and mutual benefit," and Asia is hailing the new orientation of bilateral ties and achievement set up by the leaders of the two countries.
